Abstract
The invention discloses a settlement monitoring method for a submerged structure. According to the method, pressure sensors are correspondingly arranged on foundation stabilization parts in and outside the submerged structure; in case of settlement of the structure, water pressure measured by the pressure sensor arranged on the structure in real time is changed synchronously with a settlement process, water pressure measured by the pressure sensor arranged outside the structure and a water level are kept unchanged, and a difference between changes in the water pressure measured by the pressure sensors in and outside the submerged structure is the settlement amount of the structure.
Description
Technical field
The present invention relates to the Hydraulic and Hydro-Power Engineering technical field, is a kind of submerged structure Monitoring method of the subsidence specifically.
Background technology
Along with China's Hydraulic and Hydro-Power Engineering construction develops rapidly, the large storehouse of a collection of high dam is built up successively as power stations such as voe, glutinous Zha Du.Affected by the factors such as landform, geology, hydro-structure, the engineering construction difficulty progressively strengthens, particularly important to project security monitoring and evaluation.The at present safety monitoring of hydraulic structure mainly or visible outside surface inner at dam body is carried out, and monitoring means commonly used mainly comprises vertical line, draws bracing cable, surface deformation monitoring point etc.Because monitoring range is limited, it is larger that the submerged structure settlement monitoring is implemented difficulty, causes the safety evaluation after the engineering retaining comprehensive not.
For part dam dam type as rock or core wall rockfill dam, the impact that dam facing and dam body are changed by water environment under water, the importance of its displacement monitoring is higher than other position, but be subject to the domestic monitoring to above-mentioned position of observation condition restriction not yet system carry out.Submerged structure settlement monitoring difficult point is without sighting condition, and underwater instrument bears higher hydraulic pressure load, higher to performance requirements such as instrument reliability, permanance.
The domestic settlement monitoring to submerged structure there is no the way of mature and reliable at present, is so limited relevant Specifications of Monitoring Technology this nothing is explicitly called for, and the thoroughly evaluating engineering safety is brought to adverse effect.
Summary of the invention
The objective of the invention is for domestic at present to the settlement monitoring of submerged structure there is no mature and reliable way, the thoroughly evaluating engineering safety is brought to the present situation of adverse effect, propose a kind of submerged structure monitoring method, this monitoring method has the characteristics such as principle is simple, reliable operation.
Technical scheme of the present invention is: firm position, the basis correspondence of interior of building and submerged structure outside arranges pressure transducer under water.
At the buildings dash or after being placed under water, when sedimentation occurs, the pressure transducer actual measurement hydraulic pressure of burying underground in buildings is synchronizeed and is changed with settling process, and the pressure transducer actual measurement hydraulic pressure be arranged in outside buildings remains unchanged, between submerged structure external pressure sensor and buildings pressure sensor, the difference of actual measurement variation in water pressure is settlement of building.
Submerged structure monitoring method of the present invention has the characteristics such as principle is simple, reliable operation, can solve preferably the problem in the submerged structure engineering monitoring, promotes monitoring technology and advances.
The accompanying drawing explanation
The pressure transducer that Fig. 1 is submerged structure Monitoring method of the subsidence of the present invention is arranged schematic diagram.
In figure, outside (bank slope) pressure transducer of 1-submerged structure, 2-builds pressure sensor (before sedimentation), and 3-builds pressure sensor (after sedimentation), 4-water level, h-benchmark head, H-gross head, Δ h-settlement of building.
Embodiment
Submerged structure Monitoring method of the subsidence of the present invention is that firm position, the basis correspondence of interior of building and submerged structure outside under water arranges pressure transducer.Described pressure transducer is high-precision pressure sensor.
As shown in Figure 1, during architecture construction, pressure transducer 1 is arranged in to the firm position of basement rock of buildings outside, pressure transducer 2 is embedded in to interior of building with construction, and by respective cable and pipeline with the work progress traction to more than designing water level elevation; At the buildings dash or after being placed under water, when sedimentation occurs, the pressure transducer actual measurement hydraulic pressure of burying underground in buildings is synchronizeed and is changed with settling process, and the pressure transducer actual measurement hydraulic pressure be arranged in outside buildings remains unchanged, now, between submerged structure external pressure sensor and buildings pressure sensor, the difference of actual measurement variation in water pressure is settlement of building.
Claims (1)
1. a submerged structure Monitoring method of the subsidence, it is characterized in that the submerged structure Monitoring method of the subsidence is: firm position, the basis correspondence of interior of building and submerged structure outside arranges pressure transducer under water.
